Cacao is also rich in antioxidants such as epicatechin, which increases blood flow to the brain and the muscles, giving people both a physical and an emotional kick that could help them dance for longer. Since epicatechin has also been shown to protect neurons and improve cognitive function, this is clearly a preferable option to other dance-fueling substances like cocaine and MDMA, even though cacao is unlikely to match the high generated by these drugs.
Naturally, for the drug to work, it needs to be as pure as possible, and not cut with any fillers like milk or sugar. This means that only raw cacao will do the trick, and putting M&Ms up your nose is unlikely to have any effect other than blocking up your airways.
However, this shouldn’t be taken to mean that snorting cacao is necessarily safe. Understandably, there is no scientific evidence regarding the safety profile of snocolate, as it’s never really been high on any researcher’s list. Yet as a general rule, it’s a good idea to think of the nose as a one-way system, and that while things may regularly come out of it, sending material the other way and up towards the brain is probably not a wise move.
